NAME
MooseX::Types::Path::Tiny - Path::Tiny types and coercions for Moose
VERSION
version 0.002
SYNOPSIS
### specification of type constraint with coercion
package Foo;
use Moose;
use MooseX::Types::Path::Tiny qw/Path AbsPath/;
has filename => (
is => 'ro',
isa => Path,
coerce => 1,
);
has directory => (
is => 'ro',
isa => AbsPath,
coerce => 1,
);
### usage in code
Foo->new( filename => 'foo.txt' ); # coerced to Path::Tiny
Foo->new( directory => '.' ); # coerced to path('.')->absolute
DESCRIPTION
This module provides Path::Tiny types for Moose. It handles two
important types of coercion:
* coercing objects with overloaded stringification
* coercing to absolute paths
It also can check to ensure that files or directories exist.
SUBTYPES
This module uses MooseX::Types to define the following subtypes.
Path
"Path" ensures an attribute is a Path::Tiny object. Strings and objects
with overloaded stringification may be coerced.
AbsPath
"AbsPath" is a subtype of "Path" (above), but coerces to an absolute
path.
File, AbsFile
These are just like "Path" and "AbsPath", except they check "-f" to
ensure the file actually exists on the filesystem.
Dir, AbsDir
These are just like "Path" and "AbsPath", except they check "-d" to
ensure the directory actually exists on the filesystem.
CAVEATS
Path vs File vs Dir
"Path" just ensures you have a Path::Tiny object.
"File" and "Dir" check the filesystem. Don't use them unless that's
really what you want.
Usage with File::Temp
Be careful if you pass in a File::Temp object. Because the argument is
stringified during coercion into a Path::Tiny object, no reference to
the original File::Temp argument is held. Be sure to hold an external
reference to it to avoid immediate cleanup of the temporary file or
directory at the end of the enclosing scope.
A better approach is to use Path::Tiny's own "tempfile" or "tempdir"
constructors, which hold the reference for you.
Foo->new( filename => Path::Tiny->tempfile );
